This invention relates to a removable spring clamp for securing an extrasole to footwear. 1 l i It is well-known to those skilled in the 5 artof'making and selling shoes that the soles of shoes are practicallyrendered useless or impaired and worn out excessively in manyoccupations engaged in by persons wearing same, that isfin working onand about heat ed orrough pavements, roads, floors and the like'and thatthe fibres thereof become deleteriously afiectedor burned out when sub?-jected to unusual wear and use. 7 r e It is'also known that, althoughthe main portions oft'he shoes, such as the uppers and the like, arestill in" good workable condi-' tion,'the soles become worn or burnedoutYto such an extent thatit is necessary-to discontinue the usethereofeor put' on a new sole to preserve and conserve the usefulness ofthe Worker or wearerand especially for safety, comfort and.oonvenieiiee.

The primary object of the invention isto provide a clamping meanswhereby an extra sole can be removably clamped to the ordinary sole by aseries of spring clamps that can be used for clamping an extra sole tothe ordinary sole-and removed therefrom without sewing, pegging or usingnails or the like as is customary.

A further object of the present invention is to provide a means forpreserving and saving the upper portions of the shoe by placing andclamping an extra sole over the ordinary sole of the shoe to cover theworn ortion and clamping same over and thereto y spring clampingmembers.

Another object of the invention is to provide spring clamping membersthat are pro vided with a series of prongs which impinge upon the weltor ordinary sole and the extra sole to hold the extra sole firmly incontact with the ordinary sole of the shoe.

A further object is to provide means whereby aspring clamp member can bespread under tension to easily fit over the extra sole and the ordinarysole to hold the extra sole in place and then release the lever spreading means from the clamping member.

A further object is to provide means for 1929. Serial not 370,074;

In order to secure the extra sole to the ordi- I nary sole of footwear,I provide two jleversiS ancl;9 which are shown in Fig; 411,1 the origi-29 nalpo'sition in full lines; They are provided with inclined slotslOandi 11. '--When placed upon the clampingmembersthey are adapted to bepressed toward 'eachother {against the tension of the spring-clampingmembers 5 5 and ,6 .to'spre ad same to present a mouth likeformation andwhen released, assuming the dotted line position shown inFig: 4; per--Hit ing amer-o re o nd b c tei h'eir n mal posit-ions and" P rmittheimpingement 1P3 one of the levers 8 has one end 12 formed similar to ascrew driver and that it is adapted to be inserted underneath theclamping member 6 to remove one of the clamping members from theordinary sole of the'shoe."

It will, of course, be understood that any sharp-pointed instrument canbe used for the purpose of removing the extra sole from the ordinarysole of the shoe. 7

.It will be understood that the series of clamping members 4 aremade ofspring steel preferably tempered and @made -to spread without breakingand engage the extra sole for holding it in its proper place togetherand in close contact with the ordinary sole.

It will also be noted that the prongs 7 on the clamping members can bemade of any desired length or'shape-or may be made of a series ofserrations or roughened surfaces if desired, 7 p

In order to permit the lever member 8 to fit close to the upper portionof the member 5 and operate, a portion 13 of the member 5 is cutaway forclearance. It will also be noted that the portions 5 and'6 extend fromthebody of the clamping members lat different lengths as shown morespecifically in Fig. 3, the upper portion 5 being shorter in length orextension than the lower portion 6." The upper portion5 clamps asdescribed herein' to the top of the ordinary sole'andthe lower portion 6extends in the same direction paral- 'lel thereto and over the extrasole 4; as shown in Fig. 2;

It will be noted that whenthe levers '8 and Sam releasedafterdistortingpartsfi and 6 .to open and tension same to fit over theordinary sole and extra sole, the spring clamp recovers its originalshape when released after being distorted. I

i one or more ofthe clamping members can be use of the levers 8 and 9 ifdesired when the tension of the clamping members is such as to permitsame.

Attention is further called to the fact that used if desired or thatthey may be placed in any spaced apart relation to each other withoutdeviating from the spiritof the invention. V

The yielding clamping member herein described provides means forattaching and detaching an extra sole to a worn out ordinary solewithout theuse of the conventional nails, pegs, sewing or the like andaffords a means for cheaply and economically repairing the ordinary wornor exhausted sole of a shoe and further provides'a convenient and rapidmeans of replacement by providingra new extra sole for shoes which aresubjected to excessive wear or tear or obnoxious use thereof by thewearer.
